to which the work' is usually applied, to be readily 6 Claims.

This invention relates to cementing machines: usually employed in shoe factories for cementing linings, doublers, etc. and more particularlyto become transferred to the grid. The greater portion of the operation is performed by placing: the material on the middle portion of the grid, so that this portion frequently becomes clogged with these loose fibers. As a result it frequently is necessary to remove them and to do this effectively and conveniently it is necessary to remove the grid from the machine, althoughthis operation is somewhat difficult.

Inpractice the greater portion of the work is usually performed by placing the material tobe cemented on. the portion: of the grid nearest the operator, and, at times, it. is desirable, when performing operations of this character on certain parts of shoes, to apply a heavier coating of adhesive to some portions than to others,

while other parts merely require the application of adhesive in separate dots over the entire surface, and, while this result may be accomplished by employing the insertable supplemental cement applying devices of my prior Patent No. 1,960,341

of May 29, 1934, this arrangement is not always conveniently available.

:Th'e objects of my invention are to provide a form of grid, for a machine of the type above referred to, which will enable the portion thereof,

cleaned, and which at the same time, will enable a heavier coating of adhesive to be conveniently applied to one portion than to another, when necessary, and also to enable a uniform application of adhesive to the entire surface at other times, with practically no inconvenience to the operator in making changes in the machine.

I accomplish these objects by providing the grid with a readily removable section in the middle part thereof and by providing such removable section with adhesive carrying surfaces of much greater area in one portion thereof than another, and arranging said section so that the portion of increased area may be supported in a position which will be convenient for use,.or in a position in; which it will not interfere with the use of the grid in the normal way.

For a more complete disclosure of the inven tion, reference is now made to the following specification, in connection with the accompanying drawing. in-: which- Fig. l is a plan view of a cementing grid provided with an. embodiment of my invention.

Fig- 2: is a detailplan' view of a removable grid section whichI employ.

Fig. 3 is a; sectional view at line 33 of Fig; 1.

Fig. 4 is a sectional view at line 4-4 of Fig.. 3.

Fig. 5 is a detail view of one end portionof one of the bars and Fig. 6 is a view of a. shoepart, indicating the character of work which may be performed.

Asshown: in. the drawing, I provide a grid of the so-called McMurraytype, in which a frame is provided: which comprises end sections In, which are connected by side. rods l'2, said rods passingthru grid. bars l4 having upright fingers. i=5, saidbars being spaced apart by washers IE on the rods l2,and clamped together by nuts on the ends ofthe rods.

According to my invention I provide; on the middle portion of'each rod, a sleeve [8 which extends for approximately one third of the length of the grid and which act as spacing washers in the same manner as the washers I6.

I further provide a; supplemental grid sectionwhich is composed of bars 20 thru which rods 22 pass and on which spacing washers 24 are placed, which hold the bars 20 in spaced relation in the'same manner as the washers l6, said bars 20 being clamped together by nuts on the; rods 22,v thereby providing a complete grid section, asshown: Figs. 2 and 4.. Each end: portion of. the bars 28 is provided with a,

notch 25, forming vertical shoulders at each end, the distance between which is equal to the distance 7 between the inner portions of the sleeves l8, so that the entire grid section may be placed in the space between the bars M, which directly engage the ends of said sleeves, andwill be supported on the rods l2, as shown in Fig. 3, in a position in which the top edges of bars 20 will be at the same level as the top ends of the fingers l5 of bars l4. Said bars 20 are also provided with fingers 26 for the greater portions of the length thereof, which are the same as fingers I5, and the remaining portion of each bar 20, each at the same end thereof, is provided with a continuous top edge portion 28, the length of which may be varied, a preferable length in proportion to the whole length of the bar being shown'in Fig. 3.

In practice, the supplemental section maybe readily removed for cleaning purposes, and as readily replaced, and as it may be placed with either end next the operator, it may be placed in a position in which the continuous edge por- V tions 28 may be conveniently used or not. For

example, if it is desired to have the breast edge portion of a heelvpad more heavily cemented than the other portions, the supplementalsec- 'tion will be placed in the position in which the edge portions 28 will be next the op'eraton'so that the breast portion of the heel padmay be con; veniently placed on the portions 2B,;with the 'resultthat the adhesivewillbe' applied thereto in'the manner; indicated in Fig.6.

r If the whole'piece ismerely tohave 'thece-Z ment applied thereto in dots, the position of the supplemental section will be reversedf so that 'normal'use will be conveniently'permitted.

While I have shown a form ofrmy invention which I consider. the b est'for all practicalrpur pose's,1 it; will be understood that the number of removable sections Ymay bepincreased, and that the removablejsection may be located in different portions of the gridfrom that shown.

Also' that my invention is notrlimited to the 7 comprising 'a'frame, and a grid/section com-' particular form of'cement carryingrfaces shown, and the cement carrying capacity, of different portions of the removable section may be 'substantially varied from that shown, with out departi'ng from my invention, 7
